Shows the motor designation as text.
Number of poles of a synchronous servo motor or asynchronous motor.
If the number of pole pairs is specified for third-party motors, the value must be
multiplied by 2 before it is entered.
Correlation between the number of poles, nominal speed n
N
in rpms and the
nominal frequency f
N
in Hz of the motor: B10 = 2·(f
N
· 60/n
N
).
Nominal output in kW.
If only the nominal torque M
N
is known instead of the nominal output, calculate
B11 according to the following formulas:
• Rotational motor: B11 = M
N
· n

• Linear motor: B11 = F

Nominal current in A, as per rating plate.
Nominal speed in rpm for rotational motors, nominal speed in m/min for linear
drives, as per rating plate.
Nominal voltage as per rating plate. For asynchronous motors note circuit type
(Y/∆)! Therefore make certain that parameters B11 ... B15 match!
Nominal frequency of the motor as per rating plate. Parameters B14 and B15
define the pitch of the V/f characteristic curve and thereby the characteristics
of the drive. The V/f characteristic curve determines the frequency (B15 f-
nominal) at which the motor is operated at nominal voltage (B14 V-nominal).
The voltage and frequency can be increased linearly beyond the nominal point.
The upper voltage limit is the supply voltage that is applied. STOBER system
motors up to size 112 offer the option of star/delta operation. Delta operation at
400 V makes it possible to increase output by a factor of 1.73 with an extended
adjusting range and at a constant torque. The motor requires additional current
in this connection variant. Make certain the following points are observed:
• The drive controller must be designed for the corresponding output (P
delta
= 1.73 · P
star
).
• B12 (I-nominal) is parameterized to the appropriate nominal motor current
(I
delta
= 1.73 · I
star
).
Parameter B18 shows as percentages in each control mode the reference
value on the motor side for torque and force quantities as (B20) C03, C05, E65
and E66. B18 becomes negative when the axis polarity is inverted in I03.
For synchronous servo motors, B18 corresponds to M
0
from B17. For
asynchronous motors the nominal torque is calculated from the nominal speed
and the nominal output.
